Examples of org.antlr.v4.runtime.ANTLRInputStream

org.antlr.v4.runtime.ANTLRInputStream
Vacuum all input from a {@link Reader}/ {@link InputStream} and then treat itlike a {@code char[]} buffer. Can also pass in a {@link String} or{@code char[]} to use.
If you need encoding, pass in stream/reader with correct encoding.
